Dstv DPP explorer decoder R99pm deal

I first sent an sms to DPP 32444 and got a reply back from one of the call centre agents,I completed an online application and a credit check was done and the deal was approved and the agent said that the courier company will be in contact with me to deliver the Explorer decoder.All of this was happening in December last year .I tried getting in contact with a couple of agents to find out the progress of the delivery but I had no success. It is now May 2015 and still nothing has been done, this is poor service delivery and it is becoming a waste of my time and money every time I have to send one of these sms's.The company should have the courtesy of keeping their customers informed of the progress of their application.This was one of the worst experiences I have ever had when it comes to customer service.
